Cutback bitumen is penetration grade bitumen blended with a petroleum solvent to reduce its viscosity, allowing it to be applied at lower temperatures for prime coats, tack coats and surface dressing. As trusted cutback bitumen suppliers, Bitumax offers all three curing classes — Rapid Curing (RC), Medium Curing (MC) and Slow Curing (SC) — delivering efficient, workable solutions for road construction and maintenance projects worldwide.
Cutback bitumen is penetration grade bitumen fluxed with a petroleum solvent so it can be applied cold or warm. The curing class is set by the solvent's volatility; the number denotes kinematic viscosity. Request a grade for a spec sheet and price.
Fast set for tack coats, surface dressing and cold-weather work; grades RC-70 to RC-3000.
Versatile prime coats, patch mixes and stockpile maintenance; grades MC-30 to MC-3000.
Long open time for prime coats and dust control in warm climates; grades SC-70 to SC-3000.
Chosen where a lower application temperature and controlled curing time matter — priming, bonding and maintaining road surfaces.
MC and SC grades penetrate and bind granular base courses ahead of the asphalt layer.
RC grades create a fast-setting bond between existing and new pavement layers.
Rapid-curing binders lock in chippings for cost-effective surface renewal.
Workable at ambient temperatures for fast, durable maintenance and emergency repairs.
Slow-curing grades bind unsealed roads, shoulders and haul routes.
Extends pavement life by sealing fine cracks and rejuvenating surfaces.
Cutback bitumen ships in bulk iso-tanks and in new steel drums, with full export documentation and certificates of analysis.
Our bulk Cutback Bitumen packaging ensures efficient and cost-effective transportation for large-scale projects.
For more manageable quantities, we provide Cutback Bitumen packaged securely in durable drums.
Our FIBCs (Flexible Intermediate Bulk Containers) are an excellent choice for projects requiring flexibility and ease of handling.
Match the curing class to the job and the climate. Send your application and we will recommend RC, MC or SC and the right viscosity number.
Bitumax cutback grades are produced and certified against the curing-class specifications your works require.

Cutback bitumen is penetration grade bitumen fluxed with a petroleum solvent so it can be sprayed or mixed at lower temperatures. As the solvent evaporates, the binder cures back to full strength. The curing class — rapid (RC), medium (MC) or slow (SC) — is set by the volatility of the cutter, and the grade number denotes viscosity.
Use RC grades for fast-setting tack coats and surface dressing, MC grades for versatile prime coats and patch mixes, and SC grades where a long open time suits warm-climate priming and dust control. Where a hot-applied paving binder is needed instead, choose penetration grade or viscosity grade bitumen; for waterproofing and roofing, see oxidized bitumen.
Because cutbacks contain volatile solvents, they ship in bulk iso-tanks and new steel drums under the applicable dangerous-goods rules — see packaging and logistics and shipping, and our buying process for how orders flow. Bitumax quotes FOB and CIF worldwide; buyers in Kenya, South Africa, Indonesia and India order regularly — see the full where to buy map.
